In the coming years, an increase in lung nodule resection is expected, particularly in Video-assisted thoracoscopic surgery (VATS). In some situations, it is necessary to use a device for locating these nodules. Meanwhile, the Cone Beam Computed Tomography (CBCT) is a tool whose use is constantly spreading.
The aim of this study is to evaluate the feasibility of using intraoperative CBCT to develop a new procedure for intraoperative localization of pulmonary nodules in video-assisted thoracoscopic surgery.

30
Acquisitions are performed with the DynaCT function of a C-arm Artis Zeego System® device
The anesthesia and surgery will take place according clinical routine practice
Centre Hospitalier Universitaire de RENNES

Assessment of CBCT
Ability to identify the lesion on CBCT images of unventilated lung. CBCT images are interpreted by 2 senior surgeons.
Time frame: the day following the acquisition
Feasibility of CBCT
Number of patient excluded because of an inability to achieve CBCT acquisition, whatever the reason.
Time frame: At the end of the surgery
Assessment of global image quality
Assessment of image quality is based on an "open label" interpretation of CBCT images by two senior surgeons who score images from 0 (uninterpretable) to 10 (same quality as CT images)
Time frame: the day following the acquisition
Assessment of image quality of lesions
Assessment of image quality depending on the type of lesion and their location. Interpretation of CBCT images are performed by two senior surgeons who score images from 0 (uninterpretable) to 10 (same quality as CT images)
Time frame: the day following the acquisition
